The advertised monthly is the number that gets quoted. The number that leaves your account before you have keys is the one that decides whether the place is affordable.

A 24,000 baht unit. Two months deposit is 48,000, plus the first month, and the lease totals it for you: 72,000 baht before you have keys — three months paid to move in. Parties, building and bank details removed; these terms are the market standard, not this landlord’s invention.
People assume the deposit covers the final month and stop paying. Leases here usually say the opposite, in writing, and breaking the term forfeits it entirely.

Two clauses worth reading before you sign. Leave early and the deposit is gone. Stay the term and it comes back within 30 days — and it cannot be deducted from the last month’s rent.

Not immigration or legal advice. This page explains what a landlord and a lease need to do. For the application itself, use a licensed agent or the official channels. We rent condos — that is the part we know.
